Eat small portions and cut out junk food

How can I express my meaning of lose our weight?

**Lose weight** not "lose our weight"

Move more ,eat healthy ! Moving through exercise, sports, any indoor or outdoor activities. Eat less of the unhealthy food , I need not tell you how that goes ;) Just try to accustom yourself to eating healthy . That means avoid fat and sweets ( they do become fats in your body later).Eat more vegetables,fruits and whole grains and a moderate amount of carbs.
